Nerve stimulator measuring device

Abstract

A nerve stimulator measuring device used to measure the length of electrical conduction of a nerve using a standard electrical nerve stimulator. The device includes a linear distance measuring device attached to the probes or the body of a standard electrical nerve stimulator. In one embodiment, the linear distance measuring device includes a housing mounted on one or both. Attached to the housing is a rotating wheel that is manually positioned over the skin and rotated as the handheld is moved over the skin. A display mounted on the housing is coupled to the wheel and use to indicate the total distance moved. The electrical nerve stimulator is then held so that the cathode probe is pressed against the skin over the nerve and adjacent to the desired distance shown on the tape. The electrical nerve stimulator is then activated and a reading is obtained.

I claim: 
     
         1 . A nerve conducting testing and measuring system, comprising:
 a. a handheld nerve stimulator that includes an elongated body, an anode probe and a cathode probe longitudinally aligned and extending from one end of said body;   b. a linear skin measuring device attached to said stimulator, said linear skin distance measuring device includes a means for measuring the distance the anode and cathode probes are moved to a desired location on the skin or a nerve to be tested from the electrode sensors attached to the skin; and,   c. an electric nerve signal generator connected to said anode probe and said cathode probe on said handheld nerve simulator.   
     
     
         2 . A nerve stimulator testing and measuring system, including:
 a. a handheld nerve stimulator that includes an elongated body with an anode probe and a cathode probe longitudinally aligned and extending from one end thereof;   b. a linear skin measuring device;   c. means for attaching said linear skin measuring device to said anode or said cathode probes so that the distance said handheld nerve stimulator is moved along the skin from the reference electrode is measured; and,   d. an electric nerve signal generator connected to said anode probe and said cathode probe on said handheld nerve simulator.
